Now complete the following list:


Minimum value→ 144


Q 1 → 153


Median→ 270


Q 3 → 540


Maximum value→ 629


b. The five-number summary can now be used to construct a box-and-whisker plot for part i. Be sure to provide a
scale on the number line that includes the range from the minimum value to the maximum value.


Minimum value→ 10


Q 1 → 12


Median→ 23


Q 3 → 36


Maximum value→ 58


It is very visible that the right whisker is much longer than the left whisker. This indicates that the distribution is
positively skewed.
